  1. Square Kilometre ArrayBig Data Opportunity Dr. Jasper Horrell SKA South Africa SADC HPC Workshop, 2 Dec 2013, Cape Town

  2. Outline • SKA • Precursor: MeerKAT • Opportunity: Skills Development • Opportunity: Technology Development • Opportunity: Big Data Development

  3. SKA • Planned as by far the world’s largest radio telescope array(s). Fundamental science • Extreme sensitivity • Extreme data generator • Global project. Ten member countries (5 more likely to join) • Phase 1 construction around 2020 • 30-50 years operations • Price tag in billions of Euro

  4. SKA Members • Ten countries – UK, Canada, Germany, Italy, Netherlands, Sweden, China, South Africa, Australia, New Zealand • India currently joining • Four intend to join – Japan, South Korea, France, USA • USA probably after 2020 (Decadal Review of Astronomy)

  9. Proposed SKA construction timeline • 2013 – 2016 Pre-construction, detailed design • 2014 – 2016 Members seek SKA1 funding, following establishment of cost-cap and confirmation of SKA1 scope. • 2016/17 Establishment of new governance arrangements for the SKA Organisation • 2017 Tender for and procure construction of SKA1 • 2017 – 2020 Detailed design of SKA2 • 2018 – 2021 Construction of SKA1 • 2020 Early science with some components of SKA1 • 2019 – 2021 Seek SKA2 construction funding • 2022 – 2027 Construction of SKA2 Long term project!

  10. SKA in Africa SA + 8 African Partner Countries at present

  12. MeerKAT Our design

  13. MeerKAT Foundation Pull Tests Our design

  14. Karoo Site Complex Pedestal integration shed Dish Assembly shed Bunkered & RFI shielded processor building and power room

  15. Early 2013

  16. Site Complex - Nov 2013

  17. Extended dish assembly shed

  18. Site Complex - Nov 2013

  19. Bunkered data centreNov 2013

  20. Bunkered data centresupport systems

  21. KAT-7 Science Paper about to be submitted Accepted for publication

  22. Human Capital Development

  23. Africa HCD workshop at KAT 7 site (2011) Lots of enthusiasm to work with African universities

  24. Astrophysics in Nairobi • CONGRATULATIONS TO UNIVERSITY OF NAIROBI ON FIRST 18 GRADUATES IN ASTROPHYSICS • A DIRECT RESULT OF SKA! • URGING THEM TO STAY IN THE FIELD – DO HIGHER DEGREES

  25. Post-graduate conference 2013

  26. Young Researchers

  27. SKA Pre-Construction Phase • 2013 – 2016 for SKA Phase 1 specification and design • Self-assembled consortia responded to RfPfor self-funded work on SKA1 subsystems • Work has commenced Nov 2013

  28. SKA Pre-Construction Phase • Dishes • Central Signal Processor (correlator) • Telescope Manager (monitor and control) • Science Data Processor • Signal and Data Transport • Infrastructure and Power • Low frequency Sparse Aperture Arrays • Mid Frequency Dense Aperture Arrays • Phased array- & wideband single pixel feeds • Assembly Integration and Verification

  29. The Data Challenge Science Archive Switch Switch Correlator Beamformer Science Processor Incoming Data from collectors … * SKA Phase 2 data rates are still fairly speculative

  30. SKA Science Data Processor • Consortium led by University of Cambridge • Major radio astronomy research institutes are members incl. SKA SA, ASTRON • Broad range of ICT companies expected to be involved: Intel, IBM, NVIDIA, Cray, etc • ``Open Architecture Lab’’ • RfP submission under evaluation by SKA Org • Work starting up • Phase 1 specification and design (through 2016)

  31. SKA SA Collaboration • SKA Consortia (incl. SA industry partners) • CASPER – DSP processing platforms (ROACH) • DOME - various aspects of HPC • Intel - next generation technology • IBM USA - machine learning • Nokia Siemens - data transport • CISCO • Many universities and institutes Other discussions underway

  32. SKA Opportunity • Not given on a plate • Catalyst for growth and change in Africa • New technologies, new science, new markets • Human capital development and skills - critical mass of young engineers and scientists with expertise in next-generation technologies (e.g. Big Data; digital signal processing; HPC; control etc.) and science • Strengthen fundamental and applied research • Stimulating interest in science and engineering • “Technology discussion not procurement” at this point Global endeavour, global opportunity
